WELL-CASING.

SPECIFICATION forming part of Letters Patent No. 230,829, dated August 3, 1880.

Application filed March 25, 1880. (No model.)

To all whom it may concern Be it known that we, HENRY SHEAR and HENRY M. TOOMEY, of Arcola, in the county of Douglas and State of Illinois, have invented a new and Improved \Vell-Oasing, of which the following is aspecification.

The object of our invention is to provide a new and improved well-casing which is simple in construction and elt'ective in use.

The invention consists in a well and cistern casing formed of a number of segmental sections of earthenware or burned clay, which sections are provided with tongues and grooves at the ends and with strengthening-ribs on the inner sides.

In the accompanying drawings, Figure 1 is a plan view of ourimproved well-casing. Fig. 2 is a. perspective view of one of the segmental sections of which the well-casing is formed.

Similar letters of reference indicate corresponding parts.

A well-casing is formed of a number-of segmental sections, A, formed of clay and then ,hurned,,as ordinary tiles and bricks are made.

These segmental sections A have a tongue, B, on one end and a groove, 0,011 the other end. The inner sides of these sections are provided with a central strengthening-rib, D, and with ahalt-rib at each end, so that when the sections are united a rib is formed at each vertical joint. The curvature of these segmental sections must necessarily vary according to the diameter of the well, as, likewise, the numher of sections required to complete a circle varies with said diameter.

The sections are made preferably about one foot high and about eight inches wide.

A circle is formed on the bottom of the well with the herein -described sections, and is backed up by a quantity of cement placed between the ground and the outer side of the sections. Thenextcircleisplaced upon this. The joints must be broken at every round, and in this way the well is builtup to'the top; or the circles may be made as the. well is dug out.

These sections form a cheap and durable casing for wells and cisterns, andit' backed up by cement can be made entirely water-proof. ln wells it acts as a good filter.

The ribs D and tongues B may be conical or semicircular or of any other suitable shape in cross-section.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The segmental well-casing sections A, constructed substantially as herein shown and described, with a groove, 0, in one end and tongue B in the other, and with strengtheningribs D on the inner side, as and for the purpose set forth.

2. in a well-casing, the combination of a series of segmental sections, A, provided with tongues B, grooves (J, and strengthening-ribs D, substantially as herein shown and described, and for the purpose set forth.

3. The method, substantially as herein shown and described, of strengthening the segmental well-casing sections A, consisting in providing the said sections with a central rib, D, and with halt-rib at the verticalends, as set forth.
